Route-specific score for SEA–JFK
Alaska Airlines currently has 9.7% fleet coverage with Starlink equipped aircraft, but there are no confirmed Starlink observations on the SEA->JFK route. The rollout is announced and ongoing with medium confidence, but no recent news or community sightings support higher probability on this route. Given the lack of route-specific observations, the probability is anchored to the fleet coverage ratio of 9.7%, reflecting a conservative estimate consistent with empirical data and rollout status.
